What color are the title character's dungarees in the film "Who Framed Roger Rabbit"?

"Who Framed Roger Rabbit" is a 1988 American live-action/animated mystery comedy film directed by Robert Zemeckis, produced by Frank Marshall and Robert Watts, and written by Jeffrey Price and Peter S. Seaman. Based on the 1981 novel Who Censored Roger Rabbit? by Gary K. Wolf, the film stars Bob Hoskins, Christopher Lloyd, Charles Fleischer, Stubby Kaye, and Joanna Cassidy. Set in a 1947 version of Hollywood where cartoon characters and people co-exist, the film follows Eddie Valiant, a private detective who must exonerate Roger Rabbit, a "Toon" (i.e., cartoon character) who is accused of murdering a wealthy businessman.

Roger is a slender, white rabbit with large blue eyes, pink nose, a tuft of red hair who wears red overalls, yellow gloves, and a blue yellow polka dot bow tie. He is an amalgamation of various classic cartoon characters; taking Bugs Bunny's cartoon rabbit form, Mickey's gloves, Goofy's baggy pants, Porky Pig's bow tie and Droopy's hair. Animator Richard Williams described the process of creating him like an "American flag" with the red overalls, white fur and blue bow tie so that American audiences would enjoy him subliminally.
